Your doctor has recommended you for an MRI of the pelvis (trunk bone). Magnetic resonance imaging (MRI) uses a magnetic field, radio waves and a computer to create detailed image slices (cross sections) of the pelvis. This allows the physician to evaluate different types of body tissue in the area, as well as distinguish normal, healthy tissue from diseased tissue. Our team of expert physicians, nurses and technologists is headed by Rola Saouaf, MD, Chief, Body MRI.

Before Arriving for Your Exam

If you are claustrophobic (fearful of small, enclosed areas) or experience pain when lying on your back for more than 30 minutes, your referring physician may prescribe a relaxant or pain medication to help you through the exam. The imaging physicians at Cedars-Sinai will not prescribe these medications for you.

You must must empty your bladder two hours before the exam and not void again until the exam is complete. Do not eat or drink for four hours before the exam.

We want to make your waiting time as pleasant as possible. Consider bringing your favorite magazine, book or music player to help you pass the time.

You may also bring a CD to listen to during the procedure.

Please leave your jewelry and valuables at home and wear comfortable clothing.

After Arriving

You must tell the technologist, radiology nurse and/or imaging physician of any allergies you may have.

You will be asked to fill out a questionnaire which will determine if an MRI is safe for you. People with various implants (usually metallic) or with metal in their bodies may have difficulty with an MRI, which utilizes a strong magnetic field.

MRIs of the pelvis (female).

During Your Exam

You will be asked to change into a hospital gown, and remove any metallic objects.

You will lie on the scanning table headfirst with arms at your side.

Coils (special devices to improve image quality) will be placed in or around the area of your body under study. Also, a special probe may be inserted into your rectum for detailed visualization.

The scanning table will slide your whole body into the magnet.

During the scan you will hear intermittent humming, thumping, clicking, and knocking sounds. Earplugs will be provided to help mask the noise and allow you to listen to music.

In some cases, the imaging physician requests a contrast agent (dye) to improve the quality of the images. The dye is injected into a vein in the arm, and may cause a cool sensation.

As pictures are taken, you must hold very still, and in some cases, hold your breath.
